WATCH-CAS E.

SPECIFICATION forming part of Letters Patent No. 309,158, dated December 9, 1884.

Application iiled June 7, 1884. (Model.)

To all whom. t may concern:

Beit known that I, DANIEL OHliizii, of IVaItham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in VatcirOases, of which the following is a full, clear, and exact description.

rlhis invention consists in certain improvements in watch-cases in which the movementring is provided with one or more risers constructed to project from and overlap one or both sides ofthe central shell.

It further consists in a watch-case in which the 1novement-ring is provided with one or more risers constructed to project from and overlap one or both sides of the central shell, in combination with suitable devices for connecting the parts together and to prevent their rotation, all as will be hereinafter fully described.

The gures of the accompanying plate of drawings, forming a part of this specification, illustrate the present invention, and they are all in a similarly enlarged scale.

Figure l is in part a central transverse section and in part an edge view of awatch-case with the movement removed. Figs. 2 to 13, both inclusive, are sectional views at one side only of a watch-case, and they are all in illustration of the construction of the movement ring or band and its attachment to the annulus or central shell or body in accordance with the several features of this invention 5 and Fig. 14 is a similar view to Fig. 1, illustrating detail changes of construction ofthe movement ring or band, without departing, however, from the principles of this invention.

In the drawings, A is the band or movement to contain the watch-movement. B is the central shell or annulus or body. O is the front bezel-ring, and D its crystal. E is the back bezel-ring, and F its crystal. G is the `front cap or plate. H is the back cap or plate.

The movement band or ring A interiorly is adapted in any of the usual ways, or in any other suitable way, for receiving and securing the watch-movement- (Not represented in the drawings.) This ring A exteriorly is surrounded by the annulus or central shell, B, preferably made with a recess or chamber, J, but it may be made solid, or nearly so, using a baser metal for the inner portion thereof,

and for its exposed sides or surfaces silver, gold, or other suitable metal or material.

The annulus and Inovement-ring B A may be made either ot' the same or ot' different kinds ot' metal or other material, and they are made separate and distinct from each other, the ring A being provided with a riser, K L, at the front and back sides, ab, of the annulus B, for the attachment at the front side oi' the front bezel-ring, O, and at the back side ot' a baci; bezel-ring, Il, Fig. l, or of a back cap or plate, H, Fig. 14C.

The risers K L of the movement-ring A may both be made of one piece therewith, Figs. S, I2, and I3, or either or both of them made separate and distinct from the ring, and also from the annulus and attached to the ring in any suitable manner-as, for instance, by screwing it or them upon the ring, or by other means of fastening-and this construction of the riser separate from and attached to the ring is shown in Figs. l to 7, both inclusive, Figs. 9 and l-l.

In Fig. I the riser at the front ofthe annu lus is of the ring itself, and the riser at the back of the annulus is made separate from the ring and screwed upon the outside oi' it, passing by its flange portion d into the chamber oi' the annulus, and the same construction in substance is shown in Figs. 2, '7, and Il.

In Fig. 3 the riser at the front of the annulus is made separate from the ring and attached thereto by screwing it upon the outside of the ring, and the riser L at the back of the annulus is made of the ring itself.

In Fig. 4 the riser at the back of the annulus is made separate from the ring and at tached thereto by screwing it upon the outside of the ring, and the riser at the front of the annulus is made of the ring itself and flanged, as at f, to lap over and upon the front face or side, g, ofthe annulus.

In Fig. 5 both risers are made separate from the ring, and each attached by screwing it upon the outside thereof.

In Fig. 6 the construction and attachment of the risers are the same as shown in Fig. at, and which has been described, with this exception, that the attached back riser, L, is further secured by a fastening screw or rivet, h, entered into it and the ring.

In Fig. S both risers are in one piece with ICO fli

the ring, as has been before stated, and the front riser provided with a separate ring, k, screwed upon the saine and against the front side or face, g, ofthe annulus B, and thus differing in that respect from the saine construction, substantially, of the ring with risers shown in Fig. 12, and also shown in Fig. 13, and also in the further respect from the construction shown in Fig. 12, inthat t-he ring at its back riser, L, is fastened to the annulus by a screw or rivet, Z, passing through it into said annulus, and from the construction shown in Fig. 13, in that the separate ring at the front side ofthe annulus and the riser at the back side of the annulus are both fastened to the annulus by screws or rivets m on, passing through said separate ring and said riser into the annulus.

In Fig. 9 the front riser, K, is made separate from and screwed upon the ring A, and the back riser in two parts, M N, one of which is screwed upon the outside of the ring A, en` tering into the chamber J' of the aunuliis l5, and the other, N, screwed upon the outside ol" said part lll so screwed upon the ring A, and this construction differs from that shown in Fig. 14 in these respects, that in Fig. 14 the riser K at the front is shown as in one piece with the ring, instead of a separate piece therefrom, as shown in Fig. 9, and the riser L at the back, while it is niade separate from the ring, is in one piece in lieu ot' two pieces, as shown in Fig. l), and resembling in the latter respect the back riser and its attachment showiiiii Fig. 7.

In Figs. 10 and 1l. the front riser is shown as in one piece with the rine A, and the back riser as in part made ofthe ring and in part l. made of t-lie annulus, Fig. 10 showing the bacl; riser in its part O made from the ring A., wholly surrounded by the part P thereof, made from the annulus, and Fig. 11 showing the back riser in its part O inade from the ring and its part l) made from the annulus in r continuation of each other at the exterior periphery ofthe riser. In both views, Figs. 10 and 11, a fastening screw or rivet, h, is shown as entered into and through the back riser and the annulus.

ln all oll the constructions of the ring A with risers herein particularly described, either one or both of the risers, or the part attached to or on either of them-as, for instance, the flangej", Figs. 1, et, 6, 7, 8, and 1.3- and not constituting any part of the riser itself for the use to which it is to be applied, laps over or sets against the surface of the central shell or annulus at the side of the annulus at which they are located, and where either or both of the risers so lap over or set against the surface of the annulus, and the overlapping flange j' at one side is attached to the riser by screwing it thereon, the aiiiinlus is secured to the ring, or vice versa, by the confinement tlius secured of the annulus between the so overlapping and secured parts of the ring. 1n case either riser of itself or any part attached to it does not lap over and against the corresponding side of the annulus, then the ring and annulus niust be fastened together in soine other manner-as, for instance, by fastening screws or rivets,`as shown in Figs. 10, 11, 12, and 13, and, it' desired, fastening means of this character may be used even when the risers at both sides lap over and against the sides ofthe annulus, as shown in Fig. 1.

In Figs. 1 and 14C the riser at the back of the annulus has the back plate or cap screwed to it, and the part of the ring making such riser, and which is screwed upon the ring itself, is a bezel-ring to receive the back crystal, F. Again, the front rfser receives the front bezelring, C, and, in addition, in Fig. 1 the case at its front is shown as provided with a front cap or plate, G, to be hinged to the annulus at such side,and provided with an openiiig-spring located in the recess or chamber .l ot' the annulus, all as well known.

The annulus and ring construction shown in Figs. 4, 6, S, 10, 11, 12, and 13, more espeeially referring to the shoulder at (l at the front side of the annulus, adapts the annulus for a front cap or plate to be hinged to or snapped upon the annulus, liinging being preferable, the front bezel-rin g being attached to the riser K at the front of the annulus. In inost ofthe figures both risers K L are shown as constructed for the parts which. are to be attached to thein to be screwed upon them, notably Figs. 1 to (i, both inclusive, Figs. S, 9, and 14, while in Figs. 7, 10, and 11 the back riser is adapted for the part to be attached to it to be screwed upon it, andthe front riser for the part to be attached to it to be snapped over it, and in Figs. 12 and 13 both risers are adapted for the parts to be attached to them to be snapped over them, or, in lieu thereof, they may be hinged.

It' the movement-ring is inade iii two or more parts screwed together, their screwthreads, as also the screw-thread by which the back cap or plate or front bezel. or other part of the case is attached. to the inoveinent,sliould run in the oppositedirection, which obviously would prevent the possibility of an accidental separation of the movement-ring and annulus as the said back cap or said bezel or other part is being reinoved.

The risers K L inay be secured to the inoveinent-ring A in other ways than by screwing them upon the ring-eas, for instance, by hinge, snap, or iii any other of the cominon or suitable ways proper iii inaking watch-cases or other like-articles. Again, the risers inay be .fastened to the ring by screws or rivets, or by solder or other ineans, in addition to the particular construction of thein and the ring. The risers, if attached by solder or other equivalent way, obviously beconie part or in one piece, as it were, with the inovenientringthat is, substantially so-and consequently in this description all such portions of it speaking of a riser being niade iii one piece with IOO the ring are used in their broadest sense, meaning to include the risers when made separate from the ring, but permanently attached thereto by solder or otherwise, as above indicated.

A watch-case ofthe present improved construction can be most economically made, as it then would require but very little precious metal, and that for the central shell or annulus only, which can be a mere shell, cheaper or baser metals-such as albata, nickel, brass, or other kind-being used for the movementring and the construction of risers described.

The attachment ofthe central shell or annulus and movementring can be made the more secure, if desired, by passing the screws which are to fasten the case-springs in the chamber of the annulus through either one or both risers and the annulus. Bases of the described construction may be made very heavy, and at the saine time use but a small proportion of precious metal.

It is preferable to attach the several parts of the watch-case together, or atleast all such parts as do not require to be opened for the ordinary daily use of the watch, by screwing them into place, for the reason that thejoints can be thus inadc lighter and closer and more capable of preventing the passage of dust, ai r, or moisture to the movement.

Having thus described my invention, what I. claim, and desire to secure by Letters Patent, is

l. A watch-case in which the movementring is provided with one or more risers constructed to project from and overlap one or both sides ol" a central shell, substantially as described.

2. A watch-case in which the movementring is provided with one or more risers constructed to project from and overlap one or both sides ot' a central shell, in combination with suitable devices 'for connecting the parts together and to prevent their rotation, substantially as described.

ln testimony whereof l l1 avehereunto set my hand in the presence oi" two subscribing` witnesses.
